The Fire Crab is a large, turtle-like crabcreature native to the island of Fiji.[1] It has six legs, and a heavily jewelled shell, with different colours.[1] It is able to defend itself by shooting flames from its rear end when it is attacked.[1] The Fire Crab is a protected species, and a reservation has been created to protect this species from Muggles, who would value the jewelled shell, and wizards who use the shells as cauldrons. Fire Crabs are sold and exported as pets, but the owners require a special licence. The Ministry of Magic states that a competent wizard should be able to cope with this animal.[3]Fifth years, for their Care of Magical CreaturesO.W.L., had to demonstrate how to feed and clean out a Fire Crab without sustaining serious burns.[4]

Fire Crab

Different fire crab variants exist, which can be identified by the jewels in their shells. Noted variants include shells fitted with rubies, sapphires, and emeralds.[5]

Incendio can be cast at a flipped over Fire Crab in the Gamecube version of Chamber of Secrets to kill it.

The first try to create a Fire Crab appears in the left corner of this scene in Philosopher's Stone for PC

In the PC version of Philosopher's Stone, Harry encounters a Fire Turtle in the Fire Seed Caves in the Forbidden Forest. The Fire Turtle appears to be an early version of the Fire Crab. Its look is likely due to the 'first-time creation'.
